(HealthDay News) A new study suggests that obese women get just one hour of vigorous exercise a year, while obese men don’t do much better at fewer than four hours.

The findings startled the researchers, whose main focus was finding better ways to measure how much exercise people get.

“They’re living their lives from one chair to another,” said Edward Archer, a research fellow with the Nutrition Obesity Research Center at the University of Alabama at Birmingham. “We didn’t realize we were that sedentary. There are some people who are vigorously active, but it’s offset by the huge number of individuals who are inactive.”
